Go back to Yangcheng, arrange Wei Hong's affairs, and arrange Rupert into the laboratory.

This old guy deserves to have studied controlled nuclear fusion all his life, and it took less than three days to get completely familiar with this demonstration reactor.

After taking over the controllable nuclear fusion thing from Lu Yi, he walked around the construction site like a little old man every day, helping to deal with problems and watching the world's first nuclear fusion demonstration reactor slowly improve and grow.

The acceleration of the progress of the demonstration reactor every day is undoubtedly a great spiritual encouragement and comfort for Rupert, who has devoted most of his life to the research of controlled nuclear fusion and has been separated from his wife.

After all, most of the technologies on the demonstration reactor of tomorrow were inherited and improved by Lu Yi from the WEGA, and Rupert could clearly see the shadows of WEGA and Spiral Stone 7-X on it.

"Lu, the construction of the demonstration reactor will probably be completed the day after tomorrow, but there is a problem here, I think you should pay attention to it."

Seeing that the demonstration reactor was about to be completed, but less than three days before the construction was completed, Rupert suddenly took a piece of data and approached Lu Yi with a solemn expression.

"What's the problem?"

Lu Yi was analyzing a piece of spatial data that Zhang Qing was going to Baidao City to fight the autumn wind, and looking at Rupert, whose mental state was obviously several levels higher than that of the new Yangcheng, he was a little strange what kind of problem would make this old guy so dignified.

During this period of time, Rupert replaced Lu Yi's previous things, and Lu Yi really broke away from controlled nuclear fusion and began to devote more time and energy to space projects and space gravitational wave projects.

Of course, more energy is invested in the space gravitational wave project, and the space project is led by Wei Hong's demonic madman, and after Lu Yi replenishes his manpower and financial resources, it is like a hanging, and Lu Yi does not need to worry too much about and pay attention to it, and the data model of the Orion engine was completed and given to him two days ago.

"The problem of thermal pollution."

Rupert said seriously: "The power that the earth can withstand is not without an upper limit, and when the controlled nuclear fusion breakthrough, it can be expected that the power of the entire human society will increase by leaps and bounds."

But we need to pay attention to a problem, the huge energy consumption will eventually be emitted into the environment in the form of heat, which will lead to the overall rise of the earth's environmental temperature, which is a very serious environmental problem, and may even lead to the collapse of the earth's ecology."

"Isn't this too unfounded, the sun has such a large supply of energy to the earth, and the energy released by our human activities is not even one thousandth of the energy released by the sun to the earth, which should have little impact.

After all, it has been so many years since our industrial revolution, and the overall temperature of the earth has risen by less than 0.5 degrees. ”

Lu Yi was stunned, a little unable to believe the situation described by Rupert.

"No, Lu, this is not unfounded, this is data that has been rigorously analyzed by mathematical models."

Rupert handed the data in his hand to Lu Yi and said solemnly: "We can't use the energy released by the sun to the earth as a basis, nor can we use the fact that the overall temperature of the earth has risen by less than 0.5 degrees in the century of the industrial revolution to veto the environmental hidden dangers caused by the rapid increase in the power of human society brought about by controlled nuclear fusion."

This is a fallacy! It shouldn't be the thinking of a scientist!

The energy released by the sun to the earth is thousands of times greater than that released by human activities, and even the geothermal energy of the earth is greater than the energy released by humans.

However, geothermal energy, solar energy, and even the energy released by our humans before are in a state of balance with the earth's own digestion, so the earth has not had much impact.

However, with the increase of the energy released by our human social activities, this energy balance of the earth is gradually being broken.

What's more, the excessive release of energy is almost an irreversible and irreparable result.

Lu You have been studying the space project recently, and you must have a certain understanding of the heat dissipation difficulties of spacecraft and space stations, which is the biggest problem that plagues the expansion and development of space stations.

Heat transfer, conduction, convection, radiation three ways.

Don't look at the temperature of space is very low, but don't forget that there is no heat conduction and heat convection medium in vacuum, vacuum is unable to dissipate heat, wrapping a quilt in a hot water kettle to keep warm, it will never be as good as pouring hot water into a thermos flask and relying on the vacuum insulation effect.

From this point of view, our earth is actually a large space station, and it is difficult to dissipate the thermal energy inside, it will only continue to accumulate inside.

The higher the energy we release exceeds the balance of the earth, the faster and more energy will accumulate in the earth's interior, which is manifested in the situation that the overall temperature of the earth is getting higher and higher, and the final result is the collapse of the ecological environment.

If you don't pay attention to this problem in advance, it will be too late when the trend manifests! ”

"The above reduction of carbon emissions and the reduction of the greenhouse effect is not enough to compensate for the power increase brought by the application of controlled nuclear fusion.

After listening to Rupert's serious reminder, Lu Yi checked the data in his hand, took a deep breath, and pointed to the value on the data that Rupert took and asked.

"Lu, this data is accurate."

Rupert shook his head: "I asked the scientists of the relevant atmospheric environment, and they said that the carbon emissions caused by human activities have caused the increase in the greenhouse effect, but in fact, the greenhouse effect caused by carbon emissions accounts for a very small part of the overall greenhouse effect of the earth.

It is not carbon dioxide, a well-known greenhouse gas, that causes the biggest greenhouse effect, but water!

Water vapor transpiration forms clouds in the atmosphere, which block most of the long-wave radiation from the surface into outer space, leaving the Earth's energy inside. ”

"Laying reflectors in outer space reduces the amount of sunlight that hits the Earth...... No, the problem of gravitational equilibrium at Lagrangian points exists unless each reflector is equipped with a space engine, but it is difficult to solve the difficulty of engineering construction and maintenance.

Using the principle of air conditioning to discharge ...... into outer space A few handfuls, a hair! ”

Lu Yi, who realized that the problem was serious, scratched his hair with some worry, and when he saw the scattered silk that was grabbed in his hand, he asked Rupert with some irritation: "In your expectation, if controlled nuclear fusion breaks through and is applied, how much will the total power of human civilization increase?" ”

As Rupert said, the Earth is a super-large space station, and energy will only accumulate inside, and if you want to vent heat into the outer space, the vacuum environment will not accept it.

This means that the principle of air conditioning on the earth, fans and blowers will not work.

The placement of reflectors in outer space reduces the energy power of the sun to reach the earth, and various gravitational problems will also make this project extremely difficult, which is impossible to achieve without a hundred years of hard work, and requires a lot of maintenance costs every year.

"I have counted the change data of human activity power from the industrial revolution to the present, and every time energy technology advances, the total power of human society will increase rapidly in a very short period of time, and then reach the power limit of current energy technology in a few years."

Rupert shook his head with a wry smile: "This is a problem of human nature, and it cannot be stopped by science and technology."

Therefore, I think that once controlled nuclear fusion is broken through and applied, the total power of human society will be conservatively increased by more than 20 times, and it is possible to increase it by hundreds of times. ”

"20 times!"

Lu Yi's eyes widened, if it was before today, he would probably be happy to hear 20 times.

Because this means that after controlled nuclear fusion, the production level of human beings and the life of human beings have undergone a qualitative leap.

But now, these 20 times is simply a bomb, a bomb that will bury the entire human race if you are not careful, and it is likely that it will not have time to get rid of the shackles of the planet, and it will be too late to go to the starry sky, and human beings will be extinct due to the collapse of the earth's ecological environment.

"Let's go! Just build a mathematical model according to 20 times, and analyze how much time we can have left if the total power of human society is increased by 20 times. ”

Lu Yi shouted to Rupert with some fear, and walked towards the supercomputing area of the laboratory as he took out his mobile phone to make a call.

"Help me contact scientists in the atmospheric environment and earth environment science in China, I have an emergency model analysis here and need their cooperation......"
